Title: Grinding method for semiconductor wafer
Inventor: TSUJIKAWA YOSHINOBU
IPC: H01L21/304
Filed: 1978-12-22
Abstract: PURPOSE: To grind a semiconductor wafer by such manner as covering the face of a holder in contact with the wafer with a given matter and pressing it against a rotary table.  
     CONSTITUTION: Alumina or the like with grade 3000 or so is suspended to a slurry in water or that in which glycerol is mixed i small quantities and then supplied to a device. The face of a holder 4 mounted on a rotatable spindle 3 which comes in contact with a wafer is covered with polyurethane foam 5 the front layer of which is polyurethane having a suede surface.
